Driving a center - tapped transformer with a balanced current - output DAC
The goal of this application note by Ken Gentile for Analog Devices is two-fold: To provide an explanation of the functionality of a balanced output in the context of a current-output DAC; and to provide formulas that relate the transformer turns ratio (N), the transformer load (RL), the DAC load resistors (RO) and the maximum DAC output current (IMAX).
